Analog Devices LT7171 | Demoboard EVAL-LT7171-AZ

Description

Evaluation kit EVAL-LT7171-AZ has two single-phase monolithic DC/DC synchronous step-down regulators with a 2.9V to 16V input range featuring LT®7171. The output can supply up to 40A continuous load current. The Silent Switcher® structure is incorporated into the LT7171 to minimize EMI and reduce PCB layout sensitivity. It also integrates digital power system management functionality, allowing for programmability and telemetry with a PMBus/I2C compliant serial interface. Refer to the LT7171 data sheet for more detailed information.
